Entire menu now data driven

Now desserts and drinks are also loaded dynamically from the data
rather than hardcoded.  I also changed the templating so that instead
of changing the class attribute, I use the removeClass method and get
rid of the template class, much prettier solution.

I also changed some of the names around when referencing the
containers and what not.

Next up I need to modify the CSS, because the prices look a bit ugly.
Made prices better looking

Gave some style rules to the prices so that they appear inline with
the  name/description, and also have the same color as small pizza
price.  This gives it a pretty uniform look.
